EDGE-SETTING AND HEEL-BURNISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 243,675, dated June 28, 1881.

Application filed February 21, 1881. (Model) T 0 all whom it may concern:

Be it known that I, WILLIAM F. HUTGHIN- SON, of Lynn, in the county of Essex and Cornrnonwealth of Massachusetts, have invented certain new and useful Improvements in Machines for Burnishing the Heels and Setting the Edges of Boot and Shoe Soles; and I do hereby declare the following to be a full, clear,

and exact description of the invention, reference being had to the accompanying drawings, which formpart of this specification.

Y Myinvention relates to machines for burnishing the sole-edges of boots and shoes of that class in which the burnisher is mounted in a head adapted to have free movement in all directions, and driven by power applied through pulleys and bands.

The object of myinvention is principally to simplify the construction of the head, and to avoid the jarring mot-ion communicated to the hand of the operator by having a drivingwheel in the head itself.

The main feature of the invention consists in reciprocating the block which carries the burnishing-tool by means of a rod operated by a crank-pin on a shaft mounted in a swinging frame, or some equivalent device, which ticulaily indicated in the claims.

In the drawings, Figure 1 represents a side elevation. Fig. 2 is a plan view. Fig. 3 represents a side elevation of the head and attachments, with the supporting-arm in section. Fig. 4 is across-section of the head, and Fig. 5 a front view.

In the drawings, A represents an ordinary rockingframe mounted upon a driving-shaft, a, and provided with pulleys I) c. The ordinary weight, d, may be used to counterbalance the frame and tend to keep it in vertical position. The upper part of the frame e is pivoted upon the lower frame, A, so as to be capable of motion in a horizontal plane, while the frame A swings only in a vertical plane.

The arm B, which supports the head and burnishing-tool, is pivoted to the frame e by means of a hollow-boss, g, fixed to said frame around the projecting end of the shaftf. The arm B is adapted to turn upon the frame in a vertical plane, and is steadied against lateral movement by abrace, h, which has its bearing 011 the'opposite end of the shaft f. The arm B is hollow and receives a reciprocating rod, i, pivoted to awrist-pin fixed to the end of the shaft f and within the hollow boss g. This rod projects through the shaft, and terminates between the two sides of the frame is k, which is swiveled on the arm B, so as to rock in a horizontal plane transverse to the axis'of the arm B.

In the forward end of this frame 7070 is pivoted a cross-bar, I, having a central perforated disk, m. To this disk is swiveled a head, D, preferably recessed to receive the disks and arms and prevent limited motion in horizontal plane, so as to swing thereon in horizontal plane.

The head is preferably held to thedisk by means of a handle, a, which passes through the disk and is screwed into the head. The handle maybe suspended by means ofa spring, 0, from the ceiling, or from a suitable standard, E, set in the floor.

Heretofore the burnishing-tool-has been held down to its work by pressure of the hand,and in one instance a shank. It has been proposed to hold down a shankburnisher by means of a treadle connected directly thereto. This mode of connection requires that the rapid motion of the burnisher should beimparted to the connecting-rods. I avoid this and secure the good effects of the treadle by connecting the treadle to the head-block by means hereinafter described.

To the head are attached loopsp p,which are spread sufficiently to permit the reciprocating block to pass between them. In the bight of the loops rest the bentends of prongs qq,which are set in a socket, Q, swiveled upon a rod, 4, these devices serving, by means of a treadle to which the rod '1" is attached, to draw down the head and apply pressure to the burnishingtool. At the same time the bent ends of the prongs have free play in theloops and do not interfere with the rocking motion of the head, the socket Q turning freely upon the bent end of the rod 1.

The reciprocating block to which the tool is attached is marked F. It is connected to the reciprocating rod in the arm B by means of curved bars't t, which are pivoted on pins on opposite sides of small disks 2:, pivoted on the under side of the end of the block. The bars t t are swiveled in like manner to the end of the reciprocating rod. Other means may be used to connect the block and reciprocating rod. The block reciprocates in guides in the head in any suitable way, and carries on its lower side a socket-piece, 1), into which the shank of the tool H is inserted. The tool is held by a pin, to, which is drawn out by means of a lever, 00, and pressed in by a suitable spring, so as to catch in the hole in the upper end of the shank of the tool. By pressing the lever inward the tool is removed.

The handle a is for the hand of the operator, who can thercby move the tool or turn it to any required position while the reciprocating shaft. is imparting the necessary motion for rubbing the edge of the sole.

By placing the driving-pulley in the frame, as indicated above, I simplify the construction of the head and reciprocating block and avoid the jar imparted to the hand by the rapid revolution of a pulley in the head itself. I simplify to some extent, also, the devices in other respects, and render the apparatus lighter and more easy to handle.

The devices described for connecting the treadle to the head may be modified, and the connection may be made to the arm B or to the frame 70, without any material modification of the essential part of my invention.

1 use for holding the boot or shoe during the process of burnishing the sole-edge a double jack, such as has been heretofore known. I have, however, introduced one element into the supporting-jack applicable to a single or double arm.

In some classes of work it is necessary, for easy working of the machine, to adjust the jack slightlyin orout. In order to accomplish this without interfering with the rotation, I fix upon the shaft 1 a sleeve, 2. The sleeve 2 is held upon the shaft by a pin, 3, and may be revolved thereon, but has no longitudinal movement. The hub 4 of the jack slips over this sleeve and is held upon it by means of the pin 5,which passes into a slotmade in the sleeve in a line parallel with the axis of the shaft. This permits the jack to be set in or out, and when set at any required point it is held by a set-screw, 6, in the hub, and bears against the sleeve.

Thetool shown is designed for setting edges;

but it is obvious that one for burnishing heels may besubstituted therefor, the movement being adapted equally to either tool.

I am aware that treadles connecting directly to the reciprocating tool are not new. I am also aware that an arm carrying a tool is not new, and do not broadly claim such devices.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a machinefor burnishingthe sole-edges of boots and shoes, in combination, a head carrying the reciprocating tool and pivoted in the arm supporting said head, said arm being pivoted upon an oscillating frame, a shaft in said frame driven by suitable mechanism and connected with the reciprocating tool in the head by means of suitable rod and wrist-pin, whereby reciprocating movement is imparted to said tool, said head, arm, and frame being constructed to permitthe ordinary movements, all substantially as described.

2. The combination of the shaft f, pivoted arm B, frame 70 7c, pivoted head D, the sliding block F, and the connecting-rod, substantially as described.

3. In an edge-setting and burnishing machine, the combination of the reciprocating block, the reciprocating rod, bars tt, and their swivel connections with block and rod, as set forth.

4. In an edge-setting and burnishing machine of substantially the construction described, the combination of the head D, the cross-bar I, having perforated disk on, and handle a.

5. The combination, in a jack, of the axle, the sleeve 2, held upon the said axle by a pin, and slotted, as described, and the hub connected to said sleeve by a pin and set-screw, whereby lateral adjustment is obtained, substantially as described.

6. The combination of the pivoted arm, the swinging frame, the head pivoted in the arm, the reciprocating block carrying the tool, and the treadle and connecting-rod attached directly to the parts which carry the reciprocating block.

In testimony that I claim the foregoing I have hereunto set my hand this 17th day of February, A. D. 1881.
